Give an example of a learned behavior in animals.

The example of a dog learning to sit on command through training is a clear representation of a learned behavior in animals. Learned behaviors are those that are not innate or instinctive; instead, they are acquired through experience, often involving some form of training or conditioning. In this instance, positive reinforcement, such as treats or praise, is used to encourage the dog to perform the desired action of sitting when commanded.

In contrast, grooming behavior in cats, while important for hygiene, is instinctual and not learned through experience. Migration in birds and schooling in fish are also behaviors driven by instinct, allowing species to survive and thrive without prior learning. These behaviors are part of the animals' natural instincts, developed through evolutionary processes rather than through individual learning experiences. Thus, the training aspect associated with the dog sitting on command underscores why it is considered a learned behavior.
